Abstract
The utility model belongs to a constructional device for eliminating fixed-girder gantry machine crossbeam extension, when a fixed-girder gantry machine crossbeam is connected with a column, a spring is arranged on the crossbeam and a column connecting bolt, the spring can not only be a helical compression spring, but also a butterfly spring, a gap is arranged between a bolt and a coupling hole and can contain the extension of the crossbeam, the structure can be concise, which can effectively solve the damage caused by changes of temperature of the crossbeam on the machine. The utility model has the advantages of simple structure, concise process, low processing cost and reliable effect and the like, and can be applicable to gantry machines of various large-scale fixed-girders.
Description
Affiliated field
The utility model belongs to the heavy machine tool industry, is particularly useful for solving and eliminating the large-scale crossbeam of deciding the beam gantry lathe, the flexible influence owing to variations in temperature.
Background technology
Large-scale when deciding beam gantry lathe crossbeam (particularly weldment) and column rigid attachment, because variations in temperature, crossbeam produces flexible energy and can not discharge, and makes the crossbeam transversely deforming, influences machine tool accuracy.If connecting with column, crossbeam adopts incomplete rigid attachment, promptly an end connects with column and adopts free state, though can eliminate the transversely deforming that dilatation that crossbeam produces owing to variations in temperature causes, lathe is moving or adding man-hour, be easy to generate vibration, also can influence machine tool accuracy.Certainly, ways of addressing this issue is a lot, and the simplest way is to keep temperature-resistant, and at this moment the precision of lathe is also the most stable, but cost is too high, and the general user is difficult to accept.At present, the problem that large-sized gantry machine is caused because of above-mentioned reason does not still have simple and easy and compensates easily and processing method.
Summary of the invention
The purpose of this utility model is the problem at the deficiencies in the prior art and existence, proposes a kind of technical solution easily, in order to eliminate the crossbeam of deciding the beam gantry lathe because variations in temperature and flexible utility structure device.
Solution of the present utility model is, spring (seeing accompanying drawing 2) is set on crossbeam and column attachment bolt, is provided with the gap between bolt and the connecting pore.The effect that this structure can play is that the pretightning force of spring can overcome machine tool motion or add the drag in man-hour, and does not produce vibration, can not stop crossbeam owing to stretching that variations in temperature produces again, makes the crossbeam transversely deforming little, can not influence machine tool accuracy.
According to what the utility model proposes, eliminate and decide the flexible constructional device of beam gantry lathe crossbeam, can solve crossbeam flexible influence that lathe is produced succinctly, effectively because of variations in temperature produces.And have simple in structurely, technology is succinct, low processing cost, advantage such as reliable for effect.
Description of drawings
Accompanying drawing 1: decide beam gantry lathe crossbeam and column rigid attachment and implement schematic diagram;
Accompanying drawing 2: the crossbeam that the utility model adopts connects one of schematic diagram with bolt, spring that column is eliminated variations in temperature;
Accompanying drawing 3: the crossbeam that the utility model adopts connects two of schematic diagram with bolt, spring that column is eliminated variations in temperature.
The specific embodiment
Accompanying drawing 1 decides beam gantry mobile boring milling machine crossbeam for numerical control and the column rigid attachment is implemented schematic diagram.All connection holes connect with the bolt perfect rigidity on right column 1 and the crossbeam 2.And left column 1 ' is installed disk spring 5 (as Fig. 2, shown in Figure 3) when connecting with crossbeam 2 on the bolt 4 of its all connection holes 3, gets final product (also can control the disk spring decrement) with the torque-indicating wrencg pretension.
The solution of embodiment is among Fig. 1, on crossbeam 2 and column 1 ' attachment bolt 4, increase by two disk springs 5 (seeing accompanying drawing 2), the pretightning force of disk spring can overcome machine tool motion or add the drag in man-hour, and do not produce vibration, can not stop crossbeam owing to stretching that variations in temperature produces again, make the crossbeam transversely deforming little, can not influence machine tool accuracy.In addition, can see all in Fig. 2, Fig. 3 that gapped 6 between bolt 4 and the connection holes 3, it is flexible that crossbeam 2 can be contained in this gap 6.
Accompanying drawing 3 is that the crossbeam that the utility model adopts connects schematic diagram with another bolt, the spring that column is eliminated variations in temperature.
Beam gantry lathe crossbeam stretching structure device is decided in elimination described in the utility model, and left column and crossbeam in also can the foregoing description be set to fixed connection, and the connection of right column and crossbeam is provided with telescopic structure; Perhaps two columns and crossbeam all are arranged to telescopic version, i.e. equal mounting spring 5 on the bolt 4 of the connecting pore 3 of left and right pillar and crossbeam.
Beam gantry lathe crossbeam stretching structure device is decided in elimination described in the utility model, and its described spring both can be a helical compression spring, also can be butterfly spring, can also be the spring of other applicable types.When adopting butterfly spring, one or more butterfly spring can be set on each bolt.
Beam gantry lathe crossbeam stretching structure device is decided in elimination described in the utility model, can be used for the various large-scale Longmen machine tools of deciding beam.For example gantry boring machine, planer-type milling machine, plane milling and boring machine, metal-planing machine, gantry lathe etc.
Claims (4)
1, a kind of elimination decided the flexible constructional device of beam gantry lathe crossbeam, it is characterized in that crossbeam and column attachment bolt are provided with spring, are provided with the gap between bolt and the connecting pore.
2, decide the flexible constructional device of beam gantry lathe crossbeam according to the described elimination of claim 1, it is characterized in that, crossbeam and column attachment bolt are provided with spring, gapped structure is set between bolt and the connecting pore, both can also can be arranged on simultaneously on two columns being provided with on the column.
3, decide the flexible constructional device of beam gantry lathe crossbeam according to claim 1 or 2 described eliminations, it is characterized in that described spring both can be a helical compression spring, also can be butterfly spring.
4, decide the flexible constructional device of beam gantry lathe crossbeam according to the described elimination of claim 3, it is characterized in that, when adopting butterfly spring, one or more butterfly spring is set on each bolt.
